1. A main cause for the enervative sterility of buckwheat under cultivation at high temperature are defined. 2. The enervative sterility depend on high temperature of buckwheat are described that it is impotence by incomplete-development of female, in the flowering flower organ. 3. These incomplete-development of females increased very high at above 28 C. day temperature, and it revaration-ratio and the sterility has been a very possitive correlation. 4. The male organ of such flower could not see a variation like female. The pollen of incomplete flower has, partially, decrease of the starch content, but it has a fertile-power. 5. By alternating temperature, this female deficience could give normal type. For it is, during at summer season, the flower of buckwheat at cooler night and cooler day are normal developed female flower. 6. The revaration-ratio of incomplete flower was few at cooler night than coller day. 7. As a result of our observations it is believed that the enervative sterility of buckwheat under high temperature are depend on assimilation-respiration ratio.
